在数学言语习得过程中,解题属于用环节.解题过程就是学生数学言语的表征方式与问题表征方式建立映射的过程.解题教学的重心不应放在解题方式、方法的简单呈现上,而应更多的关注表征对于解题的影响.在教学目标维度上不妨增设表征目标,借助表征能力的提升促进解题素养的提升. In the course of mathematical verbal acquisition, the problem solving belongs to the link.The problem solving process is the process of establishing the mapping between the representation of the mathematical language of students and the way of representation of the problem.The focus of problem-solving teaching should not be placed on the way of solving problems and the simple presentation of the method , We should pay more attention to the influence of characterization on the problem solving.There may be additional characterization goals in the teaching goal dimension to promote the improvement of problem solving quality through the improvement of characterization ability.
